The water extract resulted in the highest viscosity numbers, and the HCl extract in the lowest. By characterizing the EDTA extract, the hydrodynamically equivalent dispersions were shown to be pseudoplastic. The viscosity of the dispersions varied logarithmically with reciprocal, absolute temperature and showed a resistance to settling in the presence of electrolytes and ethanol. Thus, the extract may exhibit hydrocolloidal functionality in a wide variety of foods and beverages.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/36/4/271}, eprint = {https://www.ajevonline.org/content/36/4/271.full.pdf}, journal = {American Journal of Enology and Viticulture} }
